Are they abstract classes?

Solution 2

Generally, they are to either just store relevant information and keep it together, or to derive from an existing class - adding functionality without adding functions. For example a class could derive from List and add no methods:

C#

public class Students : List<student>
   {
   public string ClassName { get; set; }
   }

No wonder, I've seen such classes being used to simply store information about various entities (like structs in C++ - C# structs are quite rare) or to pass arguments many times. These classes could later be serialized, written to/read from database etc (the latter more often, it some people just love to map database structure to class structure :) ).

Hi TimberBird, can you please pass some references....

These classes I'm talking were part of the project I've been working on, and I don't have access to them any more :). Which references would you like to see? There are really tons of examples, both for mapping class structure to database structure (like this link) and for serialization (eg this one)
